Whilst it may be frustrating, with all due respect, you do not know all the circumstances that the other children who did get an HTA may find themselves in...there may be very good reasons that the Head supported them - unrelated to your child.
That is why Guest is correctly saying focus on your child's academic ability and proving that, showing that the test was a blip in an otherwise good standard. As a throwaway comment you could mention that your other child was also summerborn, didn't qualify but is doing well, so you feel confident that this child will too. You could also throwaway that you have two others in GS so the pressure to succeed on the day on the third may have been enough to tip them over into nervousness, but all these circumstances are irrelevant unless you prove academic evidence first.
Thank you for your reply. With all due respect, I imagine "their" circumstances are just as valid as mine! Unless you are one of the parents who never unfairly had a HTA, you will not understand how frustrating it is. In our primary we mostly know who will have a HTA by Y2! I am sure you know what I mean by this. Sorry to just say it as it is, but I am sure this happens in most schools but no ones ever admits it, especially those who have ensured they have secured a HTA early on by whatever means this may be
Oh well, hopefully one day HTA's will not be allowed or they will be monitored as I am sure this has happened to a few parents. Of course those parents who worked hard enough to secure a HTA will not agree. I was not one of those parents as, to be honest, I never realised the system was so corrupt! I do feel the whole dynamics of schools would change if there were no HTA's. The way it should happen to make it fair, is if a child does not pass on the day, the parents should work just as hard as I have and will have to to prove their dc's academic ability. If, as you say, there were circumstances which caused them not to pass, then they should have no problem proving they are worthy of a grammar school place, just like I had to. Sorry for any offence caused but I only say what a lot of people think!
